I really appreciate this forum. Even digging through the archives I have a couple of questions.
How did the factory install the coolant? When I installed a replacement radiator, I filled the system with what I had drained, put most of the rest in the reservoir, and ran down the road a mile. Temp got up to 215 coming home so I shut down and coasted. Another time to got the reservoir empty, but the system still wasn't full. Topped it off and added some to the reservoir, now it seems stable. I think that is the recommended 3 burps. The factory must have had a simpler method.
Next subject:
Torque vs Torque-lite. Is Torque worth the $5 to use with a bluetooth OBD adapter and my android phone?
Thanks.

The factory & Dealers use a Pump system, hook to one hose, load coolant (Dex-CooL) into the pump & the other hose to the collection machine. They pump it thru.

We can park on an incline to get the (front end) rad higher than the engine. Worst thing would be to trap air in the head. With rad higher the air tends to gravitate to the highest point.

 

We recommend the burping method to ensure all the air comes out!

It’s very simple and you are halfway through the process!

 

Torque lite is good enough for normal use. Good use for one of those old smart phones in the kitchen junk drawer.

 

The factory used the small plug to allow air to escape from the head.



The bolt between the air box stud and the valve cover bolt, it is actually a plug in the cylinder head to the coolant passages

 

Very well put about how the factory does it.
On a production line you don't have time to run an engine up to operating temp to "burp" the system.
Time is money.

 

Same @ the stealerships.
